<R59> Custom Circuits may not:
• Interfere with the operation of other robots
• Directly alter the power pathways between the battery, fuse blocks, speed controller/relay, and motor. Custom high impedance voltage monitoring or low impedance current monitoring circuitry connected to the robot’s electrical system is acceptable, because the effect on the robot outputs should be
inconsequential.
• Directly affect any output devices on the robot, such as by providing power directly to a motor, supplying a PWM signal to a speed controller or supplying a control signal to a relay module
• Be used for wireless communication, such as sending or receiving a signal to and/or from the alliance station
• Connect to the radio or tether ports on the Robot Controller

Yes--and no. You are allowed to hook them up to the OI, as per the rules in my previous post in this thread. You can have the RC tell the OI to make x device make y noise. That's legal. Having a portable computing device (laptop, PDA, etc) on the robot--the inspectors will call you on it pretty quickly, and so will the refs if the inspectors miss it.
